While Flash may have fallen by the wayside for many in favor of newer technologies like HTML5, much of the web still relies on the old plug-in to display content to users. Though macOS no longer comes with Flash installed by default, you can still download and install it if you need to. If you have Flash on your Mac, you might be wondering how to go about updating the plug-in, especially if you've decided not to allow Flash to update itself.
Here's what you do when you want to update Flash on your Mac.
How to update Flash on your Mac if you've already got it installed
- Open System Preferences from your Dock or Applications folder.
Click the Flash Player icon.
- Click the Updates tab.
- Click Check Now.
Follow the prompts that appear if Flash needs updating.
The first, and in my opinion, the best way to check and see if Flash is up to date on your system is to check directly inside of the System Preferences app on your Mac. To do that, follow these steps: 1) Launch the System Preferences app on your Mac and click on the Flash Player preferences pane. 2) When you’re in the Flash Player preferences pane, click on the Updates tab.
